#491 Descriptions of data.enumerated values

These descriptions are more (in some cases much more) flexible than their datatype (data.enumerated) in fact allows. Some aren't literally inconsistent, just potentially misleading. Some, however, are in conflict.

Discussion

These <valDesc> elements are retained from a pre-datatype version of the Guidelines and are often inconsistent or misleading in this way; they were retained in case they provided useful constraints that might be re-expressed using schematron. I have now removed the ones you list above, and there is an ongoing activity to check the remainder.
